HEAT-GENERATING GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 323,813, dated August4,1885.

Application filed July 24, 1883.

To all whom it may concern:

Be it known that I, HIRAM A. KIMBALL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphiaand State ofPennsylvania, have invented certain new and useful Improvements inBurners for Consuming Gas to Generate Heat, of which the following is aspecification, reference be ing had therein to the accompanyingdrawings.

My invention relates to burners for consuming gas to generate heat; andthe improvement consists in the peculiar manner of constructing saidburner, as will be hereinafter described, and more particularly pointedout in the claims.

Heretofore great difficultly has been experienced in mixing the gas withair in the proper porportions to insure complete combustion, and at thesame time be able to produce burners of any desired heating capacity.These'difficulties are overcomeby myimproved burner, in which the air isforced out through a number of small holes arranged in a circle andcompletely surrounding an inner central outlet for the gas. On theoutside of these air-outlets, and completely surrounding them, isanother gas-outlet, so that the air passing out of the burner isenveloped on all sides by the gas, and a complete and thorough mixtureof the two elements is thus accomplished. The flow of both air and gasbeing under separate control, the proper proportion of each is easilysecured.

In the accompanying drawings, Figure 1 represents an elevation of theinner part of the burner containing the air-passages. Fig. 2 is asection of the same part on the line A B. Fig. 3 is a cross-section onthe line 0 D. Fig. 4 is a section of the whole burner on the line E F.Fig. 5 is an elevation of the small end of the burner. Fig. 6 is anelevation of the large end of the burner.

A A represent the outer casing of the burner, which is made in two partsand screwed together at a a. B is the air-inlet.

(N0 model.)

0 is the gas-inlet. b b the passages for the air through the burner; c cthe gas-passages.

a a are the outlets for the air. a is the central gas-outlet. c is thegas-outlet around the outside of the air-outlets a a. p is an opening toconvey the gas to the central outlet, 0. The outlets a. a are circularand generally made about one thirty-second of an inch in diameter,but'the size may be varied somewhat as the pressure is more or less.They are placed equidistant from each other and from both of thegas-outlets, the distance from each outlet being about one-sixteenth ofan inch.

As gas is much lighter than the atmos- 6o phere and always under somepressure, to obtain the best results with my improved burner the airshould also be forced through under pressure. 7

It will readily be seen that by the plan 6 5 herein described burners ofany desired capacity may be made bysimply increasing the size of thediameter of the burner and increasing the number of air-outletscorrespondingly, care being always taken to preserve the rela- 7o tivesize of said outlets, and the distance between each and between the gasand air outlets.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent, is

1. A gas-burner having the air-inlet B and passages 12 b, in combinationwith the gas-inlet O and gas-outlets c and c, all substantially as andfor the purpose shown and described.

2. A gas-burner having the central gas-outlets, c, surrounded by theair-outlets a, and the whole encircled by another gas-outlet, c, incombination with the gas-inlet O and airinlet B, all substantially asshown and de- 8 5 scribed.

In testimony whereofl affix my signature in presence of two witnesses.

Correction It hereby certified that in Letters Patent No. 323,813,granted August 4, 1885, upon the application of Hiram A. Kimball ofPhiladelphia, Pennsylvania, for an improvement in Heat GeneratingGas-Burners, an error appears requiring the following correction: Inline51 of the printed specification the reference letter p should read (1,and that the Letters Patent should be read with this correction thereinto make the same conform to the record of the case in the Patent Office.I
